如何将所有python代码捆绑到一个zip文件中？

发布于 2021-01-29 15:08:51

分发应用程序时，将 所有
鸡蛋合并到一个zip文件中会很方便，这样您只需分发一个zip文件和一个可执行文件即可（某些自定义二进制文件会简单地启动，加载zip文件的主要功能并启动python关闭或类似）。

我已经看到过一些有关在线执行此操作的讨论，但是没有实际执行此操作的示例。

我知道您可以（如果它是zip安全的）将鸡蛋转换为zip文件。

我不确定的是：

您能以某种方式将所有鸡蛋合并到一个zip文件中吗？如果是这样，怎么办？

您如何从特定的鸡蛋加载并运行代码？

您将如何确保该Egg中的代码可以访问所有依赖项（即zip文件中的其他Egg）？

人们经常问这类问题，并得到类似的答案。使用py2exe。是的，我明白了，这是一种解决方案。不过这不是我要问的问题…

    您可以使用常规python工具自动执行大部分工作。让我们从干净的virtualenv开始。

    [zart@feena ~]$ mkdir ziplib-demo
[zart@feena ~]$ cd ziplib-demo
[zart@feena ziplib-demo]$ virtualenv .
New python executable in ./bin/python
Installing setuptools.............done.
Installing pip...............done.

    现在，让我们安装将进入压缩库的一组软件包。诀窍是强制将它们安装到特定目录中。

    （注意：不要在命令行或pip.conf / pip.ini中使用–egg选项，因为它会破坏文件布局，从而使其无法在zip中导入）

    [zart@feena ziplib-demo]$ bin/pip install --install-option --install-lib=$PWD/unpacked waitress
Downloading/unpacking waitress
  Downloading waitress-0.8.5.tar.gz (112kB): 112kB downloaded
  Running setup.py egg_info for package waitress

Requirement already satisfied (use --upgrade to upgrade): setuptools in ./lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg (from waitress)
Installing collected packages: waitress
  Running setup.py install for waitress

    Installing waitress-serve script to /home/zart/ziplib-demo/bin
Successfully installed waitress
Cleaning up...

    更新 ：现在pip有了-t <path>switch，其功能与相同--install-option --install-lib=。

    现在让我们将它们打包成一个拉链

    [zart@feena ziplib-demo]$ cd unpacked
[zart@feena unpacked]$ ls
waitress  waitress-0.8.5-py2.7.egg-info
[zart@feena unpacked]$ zip -r9 ../library.zip *

[zart@feena unpacked]$ cd ..

    请注意，这些文件应位于zip文件的顶部， zip -r9 library.zip unpacked

    检查结果：

    [zart@feena ziplib-demo]$ PYTHONPATH=library.zip python
Python 2.7.1 (r271:86832, Apr 12 2011, 16:15:16)
[GCC 4.6.0 20110331 (Red Hat 4.6.0-2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import waitress
>>> waitress
<module 'waitress' from '/home/zart/ziplib-demo/library.zip/waitress/__init__.pyc'>
>>>
>>> from wsgiref.simple_server import demo_app
>>> waitress.serve(demo_app)
serving on http://0.0.0.0:8080
^C>>>

    更新： 从python
    3.5开始，还有zipapp模块可以帮助将整个包捆绑到.pyz文件中。对于更复杂的需求，pyinstaller，py2exe或py2app可能更合适。
